Lub zog thiab hnav tsis kam ntawm cov hlau tshwj xeeb tau txhim kho
1.Alloying
Ntxiv cov pa roj carbon monoxide: Cov pa roj carbon yog ib qho tseem ceeb ntawm cov hlau uas txhim kho lub zog ntawm cov hlau. Ua kom cov pa roj carbon ntau ntxiv ua rau cov tawv tawv thiab lub zog ntawm cov hlau, tab sis nws kuj txo cov hlau qhov toughness. Hauv cov hlau tshwj xeeb, cov ntsiab lus carbon feem ntau tau hloov kho raws li cov kev xav tau tshwj xeeb.
Ntxiv cov ntsiab lus alloying: xws li chromium, molybdenum, npib tsib xee, vanadium, thiab lwm yam. Cov alloying ntsiab no tuaj yeem tsim cov theem nyuaj xws li carbides thiab nitrides los txhim kho lub zog thiab hnav tsis kam ntawm cov hlau.
2. Kev kho cua sov
quenching: Cua sov cov hlau mus rau ib qho kub thiab txias nws sai heev los hloov cov qauv hlau rau hauv cov qauv muaj zog xws li martensite lossis bainite. quenching tuaj yeem ua rau kom muaj zog thiab lub zog ntawm cov hlau, tab sis nws tuaj yeem ua rau cov hlau nkig. Yog li ntawd, tempering feem ntau yuav tsum tau txo cov brittleness ntawm steel thiab txhim kho toughness.
Tempering: Cov hlau quenched yog rhuab mus rau ib qho kub, khaws cia sov rau lub sijhawm, thiab tom qab ntawd txias. Tempering tuaj yeem tshem tawm kev ntxhov siab, txhim kho lub zog ntawm cov hlau, thiab kuj kho qhov hardness thiab lub zog ntawm cov hlau.
Normalizing: Cua sov cov hlau kom austenitizing kub thiab ces txias nws hauv huab cua. Normalizing tuaj yeem kho cov qoob loj ntawm cov hlau thiab txhim kho nws lub zog thiab toughness.
Annealing: Cua sov cov hlau mus rau qhov kub thiab txias, ua kom sov rau lub sijhawm, thiab maj mam txias nws. Annealing tuaj yeem tshem tawm cov kev ntxhov siab sab hauv ntawm cov hlau, txo qhov hardness, ua rau kom muaj zog, thiab pab txhawb kev ua haujlwm thiab kev kho mob.
3. Kev siv tshuab
Forging: Forging tuaj yeem txhim kho cov qauv ntawm cov hlau, kho cov nplej ntawm cov hlau, thiab ua kom lub zog thiab tawv ntawm cov hlau. Forging kuj tuaj yeem tshem tawm qhov tsis xws luag xws li xoob thiab qhov pores hauv cov hlau thiab txhim kho qhov ntom ntawm cov hlau.
Rolling: Rolling tuaj yeem ua rau cov qauv steel ntau dua, txhim kho lub zog thiab hnav tsis kam ntawm cov hlau. Nyob rau tib lub sijhawm, dov kuj tseem tuaj yeem tswj cov duab thiab qhov loj ntawm cov hlau kom ua tau raws li kev siv sib txawv.
Kev kho deg: Kev kho deg ntawm cov hlau tshwj xeeb, xws li carburizing, nitriding, chrome plating, thiab lwm yam, tuaj yeem txhim kho qhov tawv tawv thiab hnav tsis kam ntawm cov hlau thiab txuas ntxiv kev pab cuam lub neej ntawm cov hlau.
4. Microstructure tswj
Grain refinement: Cov nplej ntawm cov hlau tuaj yeem ua kom zoo los ntawm kev tswj cov txheej txheem solidification thiab kev kho cua sov ntawm cov hlau. Grain refinement tuaj yeem txhim kho lub zog thiab tawv ntawm cov hlau, nrog rau kev hnav tsis kam ntawm cov hlau.
Tsim cov theem nyuaj: Tsim cov theem nyuaj hauv cov hlau, xws li carbides, nitrides, thiab lwm yam, tuaj yeem txhim kho hardness thiab hnav tsis kam ntawm steel. Kev tsim cov theem nyuaj tuaj yeem ua tiav los ntawm kev sib tsoo, kev kho cua sov, thiab lwm yam.
Tswj kev suav nrog: Kev suav nrog txo lub zog thiab tawv ntawm cov hlau thiab tseem cuam tshuam rau kev hnav tsis kam ntawm cov hlau. Yog li ntawd, tswj cov ntsiab lus thiab morphology ntawm inclusions nyob rau hauv steel tuaj yeem txhim kho kev ua tau zoo ntawm cov hlau.
5. Kev siv cov ntaub ntawv tshiab thiab thev naus laus zis
Nanotechnology: Siv cov khoom tshwj xeeb ntawm nanomaterials, xws li lub zog siab, siab hardness, siab hnav tsis kam, thiab lwm yam, kev ua tau zoo ntawm cov hlau tshwj xeeb tuaj yeem txhim kho. Piv txwv li, ntxiv cov pa roj carbon nanotubes, nanoceramic hais, thiab lwm yam rau cov hlau tuaj yeem txhim kho lub zog thiab hnav tsis kam ntawm cov hlau.
Cov ntaub ntawv sib xyaw: Los ntawm kev sib xyaw cov khoom sib txawv ua ke, qhov zoo ntawm ntau yam ntaub ntawv tuaj yeem siv tau los txhim kho kev ua haujlwm ntawm cov hlau tshwj xeeb. Piv txwv li, compositing ceramic khoom nrog hlau tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm steel; Compositing fiber ntau cov ntaub ntawv nrog hlau tuaj yeem txhim kho lub zog thiab toughness ntawm steel.
Cov txheej txheem txheej txheej saum npoo: Siv cov txheej txheem txheej txheej saum npoo av, xws li lub cev vapor deposition (PVD) thiab tshuaj vapor deposition (CVD), tuaj yeem tsim cov txheej txheej nrog cov tawv tawv thiab siab hnav tsis kam ntawm cov hlau, yog li txhim kho qhov kev ua tau zoo ntawm cov khoom siv. hlau.
Lub zog thiab hnav tsis kam ntawm cov hlau tshwj xeeb tuaj yeem txhim kho los ntawm cov txheej txheem saum toj no. Yog tias koj xav paub ntau ntxiv txog cov chaw thov thiab kev siv tshuab ntawm cov hlau tshwj xeeb, koj tuaj yeem tiv tauj Jiangsu Tisco Meta l rau kev sab laj ntxiv. Cov kws tshaj lij yuav muab kev pabcuam tshaj lij rau koj.
